Tocll whom itnmycomern:` -Be 1t known that'I, JOHN H.l DALE, a

. citizen of the United. States, residing, at` the city'lof New York, inthe borou h of Manhattanand State kof, New Yor have invented certain new and useful Improvements inV Shade-Holders, of. which .the following 1s a .-full,.clear, and exact description.

. My invention'A relates to shadeholders for incandescent-.electriclam s, the object being to provideafcheap 'an` I-eiicient form of shade-holdl device'adapted to 'be ap lied v directly-tdt eca'sing of an ordinary amp socket.v A. e

In my 'rior Patent No. 803,883, a con` oses is shown,

' f Inalng-useof a-wire ring inc osed in a spirali .or coil sprin This 'construction gives an Velasticfor fyie ding engagement between the lamp socket and the shade. f The construc- 'l tion showninl my .Patent"No. 936,421 also f provides ayielding support for the shade holder.- l-I'n thefpresent application I pro- 'f vide a shade holder having a wire ring ;-Which`can` benlocked to form an absolutely rigid andfunyielding connection with the .lai'n socket. The present invention also in-l clu es a novel method of, supporting thev lampshadeffroin the-shadefbolder. l

.In thedrawings: Figure 1 is a perspective view of aliade holder embodying the v principles of my invention; Fig`2 `isa plan f4=5of resilient tonguesl3. '.At its lower side the f Referrin 4toftlie drawings in which a double spir view of the same, and Fi 3 1s 'asectional like' -view showing the shade ho der. in use.4

parts are osignated by thesame reference sign, 1 designates the body ofI the shadel holder 'conveniently made of sheet metal 40 spun into a. generally conical form and having. an internal reflecting surface. The lower Haring portion of the body l, is,verv

body -1 has a .groove 4in whichl is received a spring ring 5. 1 6 denotes-a ,strap for joining one convolution of the spring 5 to atongue 3 of the body 1. The tension 'of the-spring ring 5 fand the plurality/of convolutions employed impart a considerable resistance against, the

resistance' is due .not only tothe resiliency of the-wire, but also to the'fr1ct1on,`1tbe1ng 'evident that there a considerable! tan-1 tongues in case ofoutward deflection of the At itsupper .en the body 1 is beaded to low such groove 7.

l0 denotes a ring foi'med of metallic wire bent into nearly, but notquite complete. cir-` cular form and inclosed.ain the At one side an aperture 11. isl'provi ed in the,

body l, to communicate with they groove 7 and the extremities ofthe wire 10 are 'de- 'ilected at 13 and 111 to project through this Specication of Letters Patent. Patelltd Sept. 20, 1910- Anplicaticnled January 13', 1909,` ISerial-Nc. l472,003. Renewed September 14, 1909. .Serial No. 517,745.

- gential displacement of the s on the oove "7a i aperture 11.V One extremity k13 4is bent to form an eye, whilethe other extremity 14.- is bent land formed into a'. sortof hook or.latch. Y'1'5 denotes a hasp pivoted to the leye 13 and adapted to coperate .with the hookorl latch 14." The hasph 15 when engaged over;

t e ring 10 into restricted thefhool; 14, draws' relation, so that it closes'lover the bead 9 of the lamp socket, as shown` in Figl. When vthe hasp 15 lis released; the rin 10 .expands removable and the sha'devholder" is lfree from the-'lamp,socl/ret.'l -WhileI have described 'this particular meansof joining the free ends of the ring'lO together when 4desiredI do not desire tobe limited-jor re! stricted thereto, as any positive means fordetachably connecting-the ends-of the ring' 10-in rigid unyie'lding engagement, will serve .intlieu thereof.' y

The usel and operationl will. be 4obvious from the foregoing description. It is merely necessary vto push the shade holder lover the-usual flanged rim 18 `of an ordinary shade 1 9,y the l.tongues automatically claspin. 'themselves into firm en a ement, 'impelle 'by the resiliency of the ou le spiral ring 5,.

The shade holder 1 is then pushed-onto the Y -usual lamp socket 20,.:1s already described,

so that `the bead 9 is within the groove 7 of the shade holder and belo'w theplane of the ring 10'. The projecting ends of the .ring 10 are then drawn together through the i en '10'5- recess 411 by meansofthe hasp 15.I

Athe 'latterI has been4 forced'over the hook 14:',

the'ring is restricted to a perfectly definite and unchanging diameter or slze, vwhich 1s Y small enough to prevent withdrawal of the l bead 9 therethrough andl which is'r'large enough to preclude its own passagethrough 'the opening 8. As the .nature o vtheliasp -i-io t 15 i positive andwunyie'ldingj'and the' ring. 1

"negligible limits, so that a fixed "positive enitself is of rigid wire, thesedimensions are not susceptible of change except within gagement of the shade -onthe lamp socket is secured. The parts are readily detachable vWhenever desired, 'however.by a simple ma nipulation.

vVhatI claim, is: -l j L1A shade holder having an interior groove at its upperend, a ring interruptedv on oneside and received in said groove, and means for rigidly joining together fthe free ends of said ring. l

2. A shade holder having an `interior vgroove at its upperend with an adjacent opening to receive a lamp socket-,'a ring interrupted onI one side' and received in said groove, 'and means connected to one end of said ring and adapted 4to, be connected to the otherl for rigidly joining together the free 'ends of said Yring to constrictthe same to a size insuiiiciently small to pass through said '.opening, but sufficiently small to positively clasp the lamp socket.

3. A shade holder having an interior groove at one end, a ring interruptedon one side and received in said groove, means for rigidly joining together the ends of said ring Within said groove, said groove having an aperture to expose the ends of said ring and said means.

4. A shade A holder having an interior" groove at one end, a ring interrupted onlone shade holder, 'and a hasp pivoted to saidv eye and adapted to engage said hook.

In Witness whereof, I subscribe my signature, in the presence of two witnesses.
